Embodiment Construction

[0025] The above-mentioned problems associated with the distribution and use of valuable digital data can be overcome by utilizing identifiers and encryption to control access, copying and playback of digital data. refer to figure 1 , a conventional system 10 for digital data distribution 12 includes a dispenser 14, a distribution medium 16 and a data application device 18. A number of unique identifiers are associated with a corresponding number of system components of the system. For example, if the medium is a physical medium, such as an optical disc, a unique medium identifier 20 will be carried on the medium. Embedded within the digital data is a unique data identifier 22 and a unique device identifier 24 associated with the data application. These unique identifiers are used to control access to data as described below. Encryption can be used to further enhance the security of the system. According to one embodiment of the invention, the identifier is validated by pa...

Abstract

A method and system for secure distribution and access to digital data, includes providing a plurality of system components; associating a plurality of unique identifiers with different components of the system; and controlling access by the system to the digital data based on a correspondence between the unique identifiers.

Description

technical field [0001] The present invention relates to a mass production and distribution system for data, which may be encrypted or not, and capable of decryption and playback by machines using digital media. More specifically, the present invention relates to digital playback devices and storage media with embedded identifiers, wherein the identifiers provide copy and playback controls. Background technique [0002] Digital data is very convenient and well suited for distribution and copying without loss of quality. But these important features are also a threat to those who own digital data. In some commercial activities, it is necessary to strictly control the copying and playback of valuable data. For example, databases, portraits, music, and personal information are all high-value digital items for which the owner may wish to restrict access. [0003] The distribution of digital media has long had security concerns, and piracy of digital content is an important iss...
